Experimental: Nurse-led teleconsultation group
9-month nurse-led telephone-based personalized behavioural intervention.
|
Behavioral: nurse-led teleconsultation
Patients assigned to this group will receive personalized dietary and physical activity advice during 9 months. Behavioural goals and action plans will be developed in a stepwise manner in accordance with baseline levels of nutritional and physical activity adherence to recommendations. |
Active Comparator: SMS group
Behavioural intervention by means of short text messages.
|
Behavioral: SMS
Patients assigned to this group will receive a total of 150 text messages (4 to 5 messages per week during weekdays) throughout the intervention period (9 months). The content of the text messages includes advice on diet and exercise. |
- Change in fasting plasma glucose [ Time Frame: at baseline, 4, 9, and 15 months ]Change in fasting plasma glucose at 4, 9, and 15 months versus baseline
- Blood levels of HbA1c [ Time Frame: at baseline, 4, 9, and 15 months ]Change in HbA1c levels at 4, 9, and 15 months versus baseline
- Maintenance of acquired dietary and physical activity changes [ Time Frame: 15 month ]Whether lifestyle changes acquired during the 9-month active-intervention phase are maintained in the mid-term.
